Measurement Report: Effects on viability, culturability, and cells fragmentation of two bioaerosol generators during aerosolization of E. coli bacteria [PDF]

Atmospheric Chemistry and Physics
Bioaerosol is a significant element of Particulate Matter (PM) and comprises various components, with bacterial species ranking as some of the most important. Reliable and consistent bioaerosol generators are essential for the investigation of bioaerosol

Concurrently Achieving 4.6 W/M2 and 120,000 Cyclability Enabled by Extendable Swing Arms in Rotational Triboelectric Nanogenerator

Advanced Science, EarlyView.
A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

Field sampling of indoor bioaerosols [PDF]

Aerosol Science and Technology, 2019
Because bioaerosols are related to adverse health effects in exposed humans and indoor environments represent a unique framework of exposure, concerns about indoor bioaerosols have risen over recent years. One of the major issues in indoor bioaerosol research is the lack of standardization in the methodology, from air sampling strategies and sample ...

Bioaerosol sampling of patients with suspected pulmonary tuberculosis: a study protocol

BMC Infectious Diseases, 2020
Background Tuberculosis (TB) is transmitted in bioaerosols containing Mycobacterium tuberculosis (Mtb). Despite being central to ongoing TB transmission, no routine diagnostic assay exists to measure Mtb in bioaerosols.

Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

Propagation of viral bioaerosols indoors

PLOS ONE, 2021
Here we look into the spread of aerosols indoors that may potentially carry viruses. Many viruses, including the novel SARS-CoV-2, are known to spread via airborne and air-dust pathways. From the literature data and our research on the propagation of fine aerosols, we simulate herein the carryover of viral aerosols in indoor air.

Diurnal Variation in Concentration of Culturable Bacterial and Fungal Bioaerosols in Winter to Spring Season

Atmosphere, 2023
Diurnal variations in the concentrations of culturable fungal and bacterial bioaerosols were measured during winter and spring. Significant variations in concentrations of bacterial bioaerosols were observed during the day in this measurement campaign ...

Towards improving Arctic mixed‐phase cloud representation in the ECMWF model using MOSAiC observations

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Abstract The presence of Arctic clouds plays a crucial role in the evolution of the surface temperature of Arctic sea ice. However, large biases in cloud representation remain in state‐of‐the‐art weather and climate models. In this study, we use observational data from the one‐year Arctic ship campaign Multi‐disciplinary drifting Observatory for the ...

Bioaerosols in the Barcelona subway system [PDF]

Indoor Air, 2016
Subway systems worldwide transport more than 100 million people daily; therefore, air quality on station platforms and inside trains is an important urban air pollution issue. We examined the microbiological composition and abundance in space and time of bioaerosols collected in the Barcelona subway system during a cold period.

A fungal perspective: Ecological reinterpretation of short‐term temporal variation in airborne eDNA

Methods in Ecology and Evolution, EarlyView.
Abstract Airborne environmental DNA (eDNA) is a powerful tool for assessing biodiversity, but its temporal dynamics and applicability to fungi remain poorly understood. Here we discuss how short‐term airborne eDNA variation should be interpreted for fungal communities.
